JOSEPH HLADKY, OF ROSSVILLE, KANSAS.

SPREADER-CRANE.

Specification of Letters Patent.

Patented J an. 10, 1911.

Application filed July 23, 1910. Serial No. 573,404.

To all whom it may concern:

Be it known that I, JosEPH HLADKY, a citizen of the United States,residing at Rossville, in the county of Shawnee, State of Kansas, haveinvented certain new and.

useful Improvements in Spreader-Cranes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to hoisting devices, particularlyto devices forloading wagons, and has for an object to provide a crane which mayreadily be removed from the wagon when the latter is entering a barn.

A further object is to provide a crane that may be easily manipulated toload the wagon box evenly.

With the above objects in view, the invention consists of the noveldetails of construction and combination of parts hereinafter fullydescribed and claimed.

In the accompanying drawings forming part of this specification, Figure1 is a side elevation of the crane applied showing the wagon box insection. Fig. 2 is an end elevation of the crane with one of the hingedsections of the standard housing swung open. Fig. 3 is a cross sectionalview taken on the line 33, Fig. 1. Fig. 4 is a cross sectional viewtaken on the line 4-4, Fig. 1. Fig. 5 is an enlarged longitudinalsectional view of the crane. Fig. 6 is a plan view of the crane.

The reference character 10 designates the sides, and the referencecharacter 11 the bottom of the wagon box. This wagon box is preferablyprovided at its rear end with a rotary spreader (not shown).

The crane comprises a rectangular bed 12 having one side in abuttingcontact with the wagon box side 10 and having a pair of angular braces13 secured to its top face and hooked over the top edge of the wagon boxside, being then secured to the side by bolts 14. A pair of inclinedbraces 15 are each secured at one end to the bed remote from the bracesand are rigidly secured by bolts or similar connectors 16 to the wagonbox side adjacent its bottom ends. The bed 12 is thus rigidly mounted inhorizontal position upon the wagon box side.

Mounted upon the top face of the bed 12 is an annular bearing plate 17,this plate being preferably rectangular in cross section and beingrigidly secured in position by means of countersunk bolts or similarconnectors 18. Formed in the top face of the bed within the innerperiphery of the bearing plate 17 is an annular ball race 19 in which ismounted ball bearings 20 the peripheries of the ball bearings extendingupward beyond the top face of the bearing plate 17 Arranged upon the topface of the bearing plate 17 is a circular plate 21 which will behereinafter referred to as a base plate and which is provided in itsbottom face with an annular ball race 22 which receives the ballbearings. The base plate 21 is provided with a beveled periphery 23. Forsecuring the base plate 21 in position, a retaining ring 24 is mountedupon the top face of the bearing plate 17 and is rigidly secured theretoby passing the before mentioned countersunk bolts 18 through the ring24, bearing plate 17 and through the bed 12. The outer periphery of thering 24 is flush with the periphery of the bearing plate 17 and theinner periphery of the ring 24 is beveled as shown at 25, this bevelededge overlying and loosely engaging the beveled edge 23 of the baseplate 21. It is now clear that the base plate 21 is mounted forrevoluble movement upon the bed 12.

Rising from the top face of the bed plate 21 is a tubular standard 26,this tubular standard having its lower end squared as shown at 27 andthis squared portion snugly fitted into a squared opening 28 formed inthe top face of the base plate. Formed in one side of the standardadjacent its top is an oblong recess 29 in the sides of which isjournaled a sheave 30 over which latter is trained a cable 31 thatextendsthrough the bore of the tubular standard 26 and throughregistering openings 32 and 33 formed in the base plate and bedrespectively and is secured at its lower end to the winding drum 34,this latter drum being mounted below the bed 12 and having one end ofits axle journaled in a suitable bearing 35 fixed in the wagon box sideand having the opposite end of its axle terminating in a crank 36 bymeans of which the drum may be actuated and the cable wound thereupon.

Pivotally mounted upon opposite sides of the standard 26 adjacent itstop are a pair of substantially parallel arms 37 between the outer endsof which is journaled a sheave 38 over which the before-mentioned cable31 is trained, the free end of this cable being equipped with agrappling fork 39 of any preferred construction. The arms 37 are rigidlysecured together at their outer ends by a brace bolt 40 so that they actas a single integral arm, which will be hereinafter referred to as aboom 41. The boom 41 may be lowered to horizontal position in order toload the portions of the wagon box remote from the crane and may berocked to nearly vertical position to load the portions of the wagon boxadjacent the crane.

For guiding the rocking movement of the boom 41 a pair of segments 42are bolted or otherwise rigidly secured as shown at 43 to opposite sidesof the standard 26 and have their free ends disposed in alinement withand considerably above the top of the standard. The boom 41 engages theopposed faces of these segments in its sliding movement. The free endsof these segments are connected by a brace bolt 44 which limits theupward movement of the boom. For limiting the downward movement of theboom, a transverse brace bolt 45 is arranged upon the segmentspreferably at the central point of the segments so that the boom when inits lowest limit of movement will extend substantially horizontal. Aplurality of alined openings 46 are formed in the segments, theseopenings accommodating the bolt 45 which may be inserted through thealined openings 47 formed in the arms of the boom to lock the boom inany desired angular position.

For retaining the standard 26 in upright position I provide a novel formof housing designated in general by the numeral 48. The housing consistsof an oblong block adapted longitudinally to form mating halves 49 and50. These halves are each provided interiorly with a semicircular bore51, the semicircular bores co6perating to form a circular bore thatloosely receives the standard 26 when the sections are closed upon thesaid standard. The lower ends of the sections 49 and 50 terminate inflat faces which bear upon the fiat top face of the base plate 21 andthe upper ends of the sections terminate in fiat faces over which isengaged a flange cap 52 having a central circular opening 53 for thereception of the standard. This cap when in position locks the upperends of the sections together and must be raised vertically from thesections in order to permit of the latter being rocked open. A pair ofspaced hinges 54 of ordinary construction are mounted upon the sectionsand hingedly connect the sections together. Mounted upon the sectionsdiametrically opposite the hinges 54 are a pair of spaced latches 55which retain the sections closed upon the standard. Secured to thesection 50 of the housing adjacent its upper ends are the upper ends ofa pair of guy wires 56 the lower ends 'of these guy wires being engagedin hooks or similar fasteners 57 mounted upon the wagon side 1.0adjacent the wagon end boards. These guy wires 56 anchor the housing inupright position and hold the housing stationary while the standard 26and base plate 21 rotate upon the ball bearings 20.

It is evident that when the wagon is entering a barn, the crane must beremoved from its upright position. The weight of the standard 26prevents of its removal vertically through the housing 48. However, byunhooking the latches 55 and lifting vertically the flange cap 52, thehalves 49 and 50 of the housing may be rocked open so that the standard26 may be raised vertically until its squared end 27 is disengaged fromthe recess in the base plate 21 when the standard may be convenientlyremoved later ally over the top face of the base plate. The standardtogether with the hinged sections of the housing may now be convenientlystored in the bottom of the wagon until again required.

From the foregoing description taken in connection with the accompanyingdrawings, it is thought the construction and operation of my inventionwill be easily understood without a more extended explanation, it beingunderstood that various changes may be made in the form, proportion andminor details of construction within the scope of the appended claims.
